To all whom it may concern:

Be it known that 1, 30mm Vrn'ron Bron- QUIST, a. citizen of Sweden, residing at Djursholms @sby, Sweden, have invented certain new and. useful Improvements in Steam Plants, of which the following is a specification.

"It is well known that the pressure used in steam plants nowadays is increased as much as possible. But hitherto it .has not been possible to increase the pressure in egnsting steam plants beyond the maximum pressure for which the boilers are constructed. The object of the present invention is to provide means for increasin the steam pressure in existing plants. With this dbject in view, the invention consists in certain novel features and combinations of parts, as will be more fully hereinafter described, reference being had to the accompanying drawing.

1 represents a boiler constructd for a pres sure as hitherto ordinarily used from which the steam passes through thel pipe 8 for instance to the steam turbine! 9 erforming useful work in the same. Revo uble steam generator elements 4 are mounted in the furnace under the Iboiler, the water reheated in the boiler 1 being fed through t e pipe 2 by the pump 3 into mid revoluble vessels so as to evaporate in these at a considerably higher pressure, for instance "50 atmospheres, than the one prevailing in the boiler l. A r eventual superheating within the revoluhle vessels the steam is carried from the revoluble vessels through the pipe 5 to an engine working expansively, tor instance a back pressure turbine 6 wherein the highpressure steam; expands to the; ressure prevailing in the boiler 1, wherea ter it p'asses through the exhaust steam pipe 7 into the steam supply pipe 8 in order to work in the turbine 9 together with the steam from the boiler 1. As the revoluble vessels 4 are arranged within the,fire box of the 'furnace and between the fire, and boiler, it !is obvious that the superheatin of the steam occurs simultaneously with tfie heating of the water in the boiler.

Having thus described my invention it claim and desire to secure by Letters Patentz- In a steam plant of the character described, a' low pressure boiler having a fire box,.. a plurality of revoluble steam generator vessels arranged within the fire box beneath the boiler and between the same and the grate or fire, a, pipe connected with the boiler to supply preheated water to the revoluble vessels, a steam pipe leading to the boiler, a low pressurelengine connected with the steam ipe, a high, pressure engine having its on aust connected with the steam pipe, and a second steam ipe connected with the revoluble vessels and the intake of the hi h pressure engine.

. at testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
